Android开发——Android搜索框架（二）

1.创建搜索建议提供者

Android已经为我们创建了一个默认的，我们只需要继承 SearchRecentSuggestionProvider 就稍做修改就可以了。

见代码：

   1: import android.content.SearchRecentSuggestionsProvider;

   2:? 

   3: /**

   4:  * 搜索提示

   5:  * 

   6:  * @author Hanguo

   7:  * http://t.sina.com.cn/halzhang

   8:  * @version 2011-1-5上午11:51:39

   9:  */

  10: public class SearchSuggestionsProvider extends SearchRecentSuggestionsProvider {

  11:     //记住这个哦

  12:     public final static String AUTHORITY = "searchprovider";

  13:? 

  14:     public final static int MODE = DATABASE_MODE_QUERIES;

  15:? 

  16:     public SearchSuggestionsProvider() {

  17:         setupSuggestions(AUTHORITY, MODE);

  18:     }

  19: }

2.配置searchable.xml

   1: <?xml version="1.0" encoding="utf-8"?>

   2: <searchable xmlns:android="http://schemas.android.com/apk/res/android"

   3:     android:label="@string/search_label" 

   4:     android:hint="@string/search_hint"

   5:     android:searchSettingsDescription="@string/search_settings_description"

   6:     android:searchSuggestAuthority="searchprovider"

   7:     android:searchSuggestIntentAction="android.intent.action.SEARCH"

   8:     android:searchSuggestThreshold="1"

   9:     android:includeInGlobalSearch="true"

  10:     android:searchSuggestSelection=" ?"

  11:     >

  12: </searchable>

参数说明：android:searchSuggestAuthorith此属性的值就是SearchSuggestAuthorith中的AUTHORITH了。android:searchSuggestIntentAction此属性定义了当我们选中搜索提示的内容时发生的目的动作。android:searchSuggestThreshold此属性定义了至少输入几个字符时才会弹出提示android:includeInGlobalSearch是否将内容加入android的全局搜索。true，加入。android:searchSuggestSelection定义搜索时参数的占位符?
